SPECIFICATION forming part of'Letters Patent No. 236,851, dated January1- 8, 188 1. Application filed .August 25, 1880. (No model.)

To all whom it may concern Be it known that I, JAMES SIMMONS, of St.Louis, in the county of "St. Louisand State of Missouri, have invented anew and Improved 5 Ice-Box; and I do hereby declare that the followingis afull, clear, and exact description of the same.

The object of my invention is to construct the main frame and walls ofan ice-box or refrigerator so as to be readily put together or detachedfor shipment, at the same time formin g asubstantial air-tightrefrigerator; and the improvement consists in the peculiar constructionof the corner-posts and sills and their ar- I 5 rangement with respectto the double walls of the box, as will be hereinafter more fullydescribed.

In the accompanying drawings, Figure 1 is a perspective view of theice-box Fig. 2, a transverse vertical section of the same; Fig. 3, aperspective view of a portion of a corner joint; and .Fig. 4, a similarview of a portion of the sill, showing the form of the joint.

The main box A may be arranged upon the 2 5 interiorin the usual manner,and provided with adoor, B, at one end, that is fitted into the easingto form an air-tigh t joint therewith. A platform, 0, formed with azinc bottom, and drainpipe 0, leading from it, is arranged in one cor- 0nor of the box A at the farthest end of the box from the door, and iselevated some distance from the ground. The platform is partitioned 011from the main compartment of the box by slats D, so that a freecirculation of air betweenthe space above the platform and the otherportions of the box may be obtained. A small door, E, is fitted into thecasing opposite the space above the platform 0, through which the icemay be passed into the box and placed upon the platform. The casing ofthe box A is extended at one corner to form a small rectangularcompartment, F, annexed to and communicatingwith the main compartment orbox A. A partition,- G, of rectangular shape, is

arranged to slide between hollow walls of the box A, and is connectedwith a door, F, coverin g the compartment F,by means of -a string orcord, H, that passes over a roller, H, in the main walls of box A, sothat when the door F is raised the partition G will be allowed to dropandshut 0E communication between the maincompartment or box A and theannexed .rents of air from the outside to rush in and reduce thetemperature in the main compartment.

The walls and framing of the structure are built up in a peculiarmanner, as follows: The sill and cap pieces may be of similar form andconstruction. The main sill-piece I is formed from a rectangular oblongpiece of timber. It is beveled at i, on its upper and outer edge, and isgrooved at 11in the middle portion of its upper face. A tenon or tongue,6 is formed on its inner and upper side to constitute a bearing for adouble floor, so that the under side of the lower floor will be flushwith the under side of the sill-piece. The sill-pieces are formed ofsides that are miter-jointed at the corners, so that the groove 6 in onesill-piece will communicate with the corresponding groove in the othersill-piece.

Each corner of the structure is provided with corner-posts K L. The postK has two tongues, k it, one formed upon each end. The one extendingoutward from the corner k forms a bearing to which the inner and outer,walls of the box A are fastened,'to leave an airspace, M, between them,and the other tongue, k, of the post fits tightly into a groove cut intothe post L, the said tongue or tenon It being cut in line with the innerwall of the box to form a flush joint with the inner side of the post.The post L has a groove, 1, cut in its face, into which the tongue ofthe post K fits snugly, and has a tongue, I, out upon its end to extendoutward from the corner to form a hearing, as in K, for the outer wallsof the box A and annexed compartment F. Screwbolts N are run throughpost L, so that they will pass through the tongue k of post K to 100secure the two posts, with their connections, firmly together. Afilling-piece, a, is secured between the outer walls, a a, at theirlower edges, to project downwardly therefrom and fit snugly into thegroove 6 in the sill and cap pieces. The posts K L are each alsoprovided at their ends with a tongue in line with and equal to thethickness of piece a and inner wall, a, which tongue fills up the groove1' at 10 the corners. The inner sides of the walls a a are covered withnon-conducting material.

The advantages of the mode of connecting the framing and walls of thebox will be readily understood, and combine simplicity, strength,

and perfectly air-tight joints.

What I claim as new is 1. The framing of an ice-box or othercompartment, formed with non-conducting walls, and consisting of thepost K, formed with tongues k k, and the post L, formed with a tongue,l, and a groove, l, to receive tongue k, the tongues k and I beingsecured to and interposed between outer and inner walls of thestructure, substantially as described.

2. The framingof an ice-box or non-conduct- :5 ing compartment,consisting of the posts K L, formed with tongues upon their lower ends,outer walls, a, inner walls, a, filling-piece a, and acap or sill piece,I,formed with groove '5, to receive the tongues upon the lower ends ofposts K L, and tongue 1?, upon the upper and inner side of thesill-piece I, to receive the outer and inner parts of a double floor, inthe manner and for the purpose substantially as described.
